GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 265,661, dated October 10, 1882 i Applicationled September 28, 1881. (Model.)

.binders where a straw band is used for binding thegavel; and the novelty consists in the construction and arrangement of parts, as will vbe more fully hereinafter set forth, and specifically pointed out in the claims.

ln the drawings which form a part of this specification, and wherein like letters indicate like parts, Figure lis a perspective view of the frame of my machine with the operating parts removed. Fig. 2 is a vertical central section on line x x of Fig. l, with the operating parts in place. Fig. 3 is a plan view of the machine, taken below a horizontal plane which passes 'through the line y y in Fig. 2. Fig. 4 is the same view as Fig. 3; but the trainof gear-wheels which give motion to the various parts are only shown in dotted outlines, so as to expose to view portions of the machine otherwise hidden from view. Fig. 5 is a vertical cross-section of the machine on line z z in Fig. 2. Fig. 6 is a detail perspective view of the under side of the head of the binding-arm.

In the drawings, A represents the frame which gives support to the entire mechanism of my binding apparatus. The space contained therein is divided in an upper and lower section by the platform-sections B and C, which together constitute the grain-bindingplatform, and between which is an opening, D, which completely divides the two sections B and C, and is wide enough to give passage to the binding-arm. The platform-section B gives support to the grain end of the sheaf, and, for purposes hereinafter explained, it is inclined, being slightly higher on its inner edge. The platform-section U is inclined in an opposite direction, as .shown in section, Fig. 2. It is also slightly raised above the platform B, and by supporting the butt-end of the sheaf the latter is rmly supported during the operation of binding. The platform-sections B and C, together with the sides of the frame A, form an inclosed receptacle, only open at top and in front, giving access thereto for feeding and discharging the sheaves.

E is the curved binding-arm, to which is adjustably secured, and forming a rear extension thereto, the spring compressor-arm F, both being connected to the crank G, secured to the shaft H, journaled in proper bearings in the frame A. The binding-arm E and compressor F form one continuons curve eccentrically to tieir center of motion around the shaft H, the free end of the compressor-arm having the shortest radial distance therefrom. The bilidng-arm E has formed on its forward end the loop a (see Fig. 6) and the slit head I, the slit b in which is provided with aflaring moutl1,c, and its cross-section is shown in Fig.2 as forming two or more distinct throats, e c, for the purpose of properly grasping and holding the 2 are secured upon the shaft g, Fig. 2, which is stepped into the frame A at h and held at z' by a lever, L,` which, when in the position shown in dotted lines in Figs. 3 and 4, brings the bevel-pinion 3 and bevel-gear wheel 4 in engagement; but when in the position shown in full lines, which also corresponds with its position in Fig. 2, the bevel-pinion 3 is disengaged from the bevel-gear wheel 4. The lever L is pivoted at 7c, Figs. l and 3. Its free end is connected to the rear side of the frame A by a tension-spring, l, Fig. 3. Pivoted upon the lever L is the locking-latch m, the hooked end n of which engages with the stop o when the lever L is drawn into the dotted position shown in Fig. 3, and which operation is performed by the operator of the machine in a convenient manner by means of a lever or otherwise. As soon as the bevel-pinion 3 and bevel-gear wheel 4 are in engagement the latter will commence to rotate; but as soon as one revolution is performed the detent p, attached to the bevel-gear wheel 4, will release the hook u of the locking-latch m from the stop o, and the parts will resume their former position, owing to the tension of the spring l.

IOO

The motion of the binding-arm E is therefore limited to one revolution, and its direction is indicated by an arrow in Fig. 5. To prevent its moving backward accidentally, a spring, q, engages into the loop a ofthe binder-arm, holding it in the position shown in Fig. 5, in which the binder-arm is held when at rest.

M is a plate, pivoted at r, Figs. 2 and 4, to the frame of the machine on the space below the platform C. This plate M has around its pivotal point r a limited horizontally-oscillating movement, allowing it to assume one of the two positions shown in Figs. 3 and 4, respectively. 111 Fig. 4 the plate M is held in its position by the rod s and chain t, which connect its npturned rear endiwith the lever L, the spring u exerting its tension to keep the rod s and chain ttaut. The plate M, when in the position shown in Fig. 3, is held therein by the locking-latch t, which is pivoted upon the plate M at w, engaging with its hooked end into the recess o.

N is the pinion-twister, which is provided Vwith two slots, a a', of ogee form, Fig. 3, op-

posite each other and extending from the circumference till near the center. Four frictionwheels, b b2 b3 b4, carried on cross-bars and posts upon the-plate M, Fig. 4, hold the pinion-twister in place and allow it to freely rotate around its center.

In Fig. 3 is' shown a train ot' intermediate spur-wheels and bevel-gear wheels, (marked 2 5 6 7 8 9 10 11 12 13,) which transmit motion trom the main shaft and impart to the piniontwister a rotary motion. The spur-wheel 12v is carried on a post, c', upon the plate M, and carries on its upper side a volute spring, 0, which during the proper rotation of the spurwheel 12 is woundup. The underside of said wheel is provided with a pin, d', Figs. 4 and 5, which, as soon as the spur-wheel has made one whole revolution, strikes the hooked latch c, disengages it from its stop o', and thereby allows the plate M, owing to the action of the spring u, to assume the position shown in Fig. 4 and part its mesh with the spur-Wheel 1l. Instantly the action of the watch-spring O will rotate the spur-wheels 12 and 13 and piniontwister in an inverse way and bring the latter back intoits old position-thatis, with the slots a' a in the position shown in Fig. 3-where the binding-arm in its travel is enabled to enter the straw band into said slots. Under the inner end of the platform C is located the horizontal shaft P, journaled in the rear side of the frame and in a bracket, c', which also serves las a support to the platform C.

To the front end of the shaft P is attached the tucker R (shown in Figs. 2 and 5) in the form ofa two-pronged claw, the two curved prongs ff being far enough apart and in proper position to straddle the twisted straw band and tuck it into the bundle, in the same way as it is done in binding by hand, by rotating said tucker upon its shaft P from the position shown in Fig. 2 in full lines into the dotted position and back again. rlhis oscillation of the tucker is caused by the following devices g is an arm secured upon the shaft P and engaging in the segmental slot h in the gearwheel 17, Figs. 2 and 3, which sits loosely upon the shaft P and derives motion from the spurwheel 12 through the intermediate bevel-gear wheels, 15 and 16. As soon as the spur-gear -17 begins to revolve the arm g will travel through the slot h without imparting any rotation to the shaft P; but as soon as the arm g has traveled through the slot h the shaft P and tucker R will revolve and continue so until the plate M, as afore described, passes from its position in Fig. 3 toits position in Fig. 4, when the bevel-gear Wheel 16 releases its mesh with the spur-wheel 17, the latter instantly beginning torotate in an inverse manner, being actuated thereto by a weight, Q, attached to the cord i', passing over a sheave, j, and attached to the spur-wheel 17, which latter, during its rotation, had wound the cord i upon the sheave k. This reverse movement of the spur-wheel 17 carries the tucker R back into its former position. The tucker R, during its upward rotation, will easily introduce its prongs into the sheaf, carrying the twisted straw-band ends along and tucking the same into the sheaf under the band in the wellknown manner, the bar S, having loop l', Figs. 2 and 5, serving as a point of resistance. The inclination of the tables VP and C aids the tucker to introduce its prongs into the sheaf. Attached to the tucker at mf, Figs. 3 and 5, is therod n', which connects the tucker 1t with the horizontally-reciprocating knife T, Figs. 3, 4, and 5. The knife T is held in position by the guides pp,and is put in such position to enable it to cut the straw band close upon top of binder-head I, Fig. 5. As soon as the tucker begins to rotate the knife T will be carried forward by its connection therewith and sever the band in advance of the action ofthe tucker, which in its reverse movement willalso carry the knife back into its former position.

IOO

1n practice, the straw band isintroduced into the slit head of the binder-arm E. As soon as a sufficiently large gavel for binding is collected upon the binding-platform the lever L is thrust by the operatorinto the position shown in dotted lines in Fig. 3.` This will, if motion is given to the machine, transmit the power from the pinion 1 to the bevel-gear Wheel 4 and rotate the bindin g-arm, encircling the sheaf with the straw band, and entering the latter also in both slots of the pinion-twister. The detent p on the bevel-gear .wheel 4 having unhooked the latch m, the binding-arm will cease its motion as the bevelgear 3 falls out of gear, but at the same time the bevelgear 2 falls into gear with the bevel-gear 5 and conveys motion to the pinion-twister, as the operator, by acting upon the lever L, has likewise, by the connection s and t, thrown the plate M into the positionin which spur-wheels 11 and 12 are meshing. Owing to slot 7L in IIS IZO

the spur-wheel 17, the tucker 2 and knife T will fall in their movement sufficiently behind the movement of the pinion-twister to give this latter ample time to start its work before the action of the knife and of the tucker begins. As soon as the spur-wheel 12 has made one revolution it will part its engagement with spur-wheel 1.1 and spring O, and weight Q will bring the pinion-twister, tucker, and knife each to their` former positions. `The bound sheaf is now ejected from the machine, and the above-described operation of binding will be repeated as soon astheoperator thrusts the lever L in the proper position.
